Supplementary Analysis: Co-occurrence Maps of Keyword and Abstract Corpora

In the main manuscript, we provided a selection of co-occurrence maps (i.e. a general map of the keyword corpus and a general map of the abstract corpus). We further presented maps for specific terms (i.e., “Islamist”, “far right,” and “far left”) derived from the abstract corpus only.
In this supplementary material, we present all specific co-occurrence maps generated from both the keyword corpus and the abstract corpus.
Recognizing the critical importance of the adolescent age group in the context of radicalization, we further provide detailed co-occurrence maps for the term “adolescence” to shed light on the key concepts and associations related to this key demographic.
